07.5 2500 HD. 12 MPG avg with 1 rig. 15 MPG avg empty.
I am pretty sure I got some bad fuel in Harlan also. The tank I ran coming back home the truck felt funny. Stopped in Greenville to fill up and it was slick as a button the rest of the way down 25.
Also, that tank of fuel cost $3/gallon. Jews. Luckilly it was only half a tank. I basically filled up twice and did two half tanks but have a whole tank left. Make sense?
